SYRINGE.

Application 'filed February To all 'whom it 'may concern:

Be it known that I, VILLIAM RICHARDS, a citizen of the United States of America, and a resident of IVarren, in the county of Warren and State of Pennsylvania, have invented a new and Improved Syringe, of which the following is a description.

My invention relates to a fountain syringe and is more particularly embodied in a rec-- tal syringe.

In the entering of the usual form of rectal syringe the operation is attended in many cases with discomfort and pain to the patient particularly in cases where there is a rectal deformation due to operations or otherwise.

The general object of my invention is to provide a syringe with a discharge and nozzle assemblage which will minimize or completely prevent discomfort and pain by reason of its mode of application, the arrangement being characterized by an element placeable by hand into the rectum and arranged to receive a metal member on the syringe head to coact therewith so that the element emplaced in the body will be held by the sphincter muscles and in the entrance of the coacting element metal will engage metal instead of metal engaging the flesh with the result of injuring or tearing the same.

The nature of my invention and its distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood thatv the drawings are merely illustrative of one example of the invention.

Figure 1 is a vertical section of a rectal syringe embodying my invention;

Figure 2 is a horizontal section on the line 2 2, Figure 3; Y

Figure 3 is an elevation of the nozzle.

In the illustrated example of my invention, the numeral 1() indicates a fragment of a bag having, as usual, a flanged nipple 11 and cap nut 12 fixed to said bag, the cap `nut 12 receiving the usual head 13 having a plug valve 14 is provided with an elongated llateral handle 15, the parts referred to being known.

In accordance with my invention I provide on the head 13 instead of the usual nozzle a tubular standard 16 being threaded at its lower end as at 17 to screw into the top 10, 1925. serial No. 8,266.

of the head 13. I provide a nozzle 18 having a tubular shank to receive the tubular standard 16, and form the base 19 of said nozzle flaring or dome-shaped to rest upon the tapered upper end of head 13. The upper portion of the nozzle 18 is enlarged as at 2O and formed at several sides with lateral discharge orifices 21 for the medica ment. The terminal end 22 of nozzle 18 is' given a blunt rounded formation to facilitate its entrance into the body.

By the described construction, the nozzle 18 may be anointed and its shape enables it to be readily entered and emplaced in the rectum even when the latter is deformed. Then, with said nozzle 18 emplaced the element 16 may be caused to enter the nozzle by the person assuming a seating posture. The flaring dome or apron portion 19 assures the ready guidance of the standard 16 into the cylindrical portion 18 of the nozzle after the nozzle has been applied to the rectum. Thus, the emplacing and use of the device is attended by no discomfort nor injury to the person. It will be seen that the nozzle 18 has support on the head 13 and is strengthened and reinforced by the presence at the interior of the tubular standard 16 to properly maintain the assemblage for effective functioning.

I would state furthermore that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claim.

Having thus described my invention, I claim:

In a syringe, a tubular standard having means to secure it to thesyringe head on a bag, and a nozzle having an intermediate cylindrical portion fitting said standard, said nozzle having an enlarged flaring base below said cylindrical portion for guiding the nozzleinto proper engagement with the standard and adapted to contact with and be supported on the head of the bag and having the enlarged upper end beyond said cylindrical portion formed with discharge orifices, the terminal of said nozzle having blunt rounded lines.

WILLIAM RICHARDS.
